How adorable is this ... to celebrate Pau Gasol's 42nd birthday, Vanessa Bryant shared video of the former NBA star trying to do ballet -- with her and Kobe's 5-year-daughter.
It's unclear when the footage was taken ... but Bryant posted the clip Wednesday morning on social media, showing the 7-foot-1 power forward, rocking a 'Kobe 24' T-shirt, trying his hardest to mimic Bianka's dance moves.
It's hilarious! You can even hear Gasol's wife Catherine McDonnell -- who captured the Kodak moment -- laugh at her hubby while giving him some ballet advice.
